SIPHON APPARATUS.

SPECIFICATION forming part of I etters'Patent No. 643,605, datedFebruary 13, 1900.

Application filed A ril 21, 1899.

to art to which it appertains to make and use the same.

This invention relates to means for filling or partially filling smallreceptaclessuch as bottles, for example-from a cask or other x largervessel containing a supply of liquids,

and especially where a series of like small receptacles have a knowncapacity when filled to a certain height.

In the drawings, Figure 1 shows in elevation the apparatus as it appearsin use, al-

though With the flask somewhat lower than it would be held while theliquid is passing. Fig. 2 is an enlarged section through a certainstopper. Fig. 3 is an enlarged detail view of 2 5 part of a certaintube.

In the figures, A represents a cask, and B a small flask or bottle in aplane at some distance below the level of the liquid in the cask. Fromthe interior of the cask to the interior 0 of the bottle passes a tube 00, usually wholly or partly of rubber, having at a suitable distancefrom its lower end an enlargement D in the form of a conical stopperadapted to fit closelyin the mouth of the bottle. In this 3 5 stopperslides a second closely-fitting tube E, of suitable material, normallyopen at both ends and having marked upon that portion which slides inthe stopper a suitable scale or scales FF. Each scale is such as toindicate o correctly the amount of liquid contained in a flask of agiven size when the surface G of the liquid in the flask touches thelower open end of the sliding tube. The apparatus being adjusted asshown, air is exhausted from the empty flask through suction at theouter end of the sliding tube, and the liquid in the cask flows over inthe tube 0 C, which then acts as a siphon until the liquid dischargedsemi No. 713,932. on) model.)

in the flask rises to and closes the inner end of the slidingtube,preventing further escape of air-.; The flow is thus arrestedautomatically, and the siphon being raised for an instant the flask maybe removed and replaced by another, and so on. If the tube be-of smallbore and such that the liquid will not readily wet its surface, theliquid will not rise within it; but otherwise it will rise to the levelof the liquid in the cask. In the latter case the u pwardly-extendingportion of the tube must be made longer or the flask 'must be so heldthat the tube rises above the level in the cask.

The conical form of the stopper of course compensates variations in theform or size of mouths of different bottles. The small tube is usuallyof rubber, the graduated stem be ing of hard rubber; but where thenature of the liquids makes it desirable other material may be used, andin some cases the tubes are of glass or are lined with glass or coatedwith paraffin.

For exhausting the air an air-pump H and valve H may be used at theouter end of the sliding tube, and for preventing flow through thesiphon while the bottles are being changed a cut-ofi I may be employed,thus obviating the necessity for raising the apparatus.

WVhat I claim is The combination with the stopper having internal upwardand downward extensions, of the siphon-tube having its channel extendedthrough said extensions and stopper, a cut off for this tube above thestopper, a normally-open tube passing through the stopper, fittingandsliding therein and having scalemarks to indicate at the surface of thestopperthe capacity of a given flask when fllled to the lower end ofsaid tube, and means for exhausting air from such flask through the tubelast mentioned.

In testimony whereof I aflix my signature in presence of two witnesses.
